Skin is something most people take for granted, after all everyone has it, right? So to help get some perspective on how amazing skin really is, a few statistics about skin are provided- by the numbers.
Keep in mind, most of these numbers are generalized (approximate, and on average) but they do apply to each individual in their own way. Try not to impress too many of your friends at parties with these facts, and be warned it might not make the best dinner conversation.
